With the escalating amount of gene expression data being produced by microarray technology, one of important issues in the analysis of expression data is quality assessment, in which we want to know whether the one chip is artifactually high or low intensity relative to the majority of the chip. We propose a graphical tool implemented in R for visualizing distributions of two gene chips. Moreover, a statistical test based on chi-square test is employed to quantify degrees of array comparability for pairwise comparisons on a large number of arrays.
In summary, this review has illustrated that our current understanding of the molecular aspects of human fertilisation is very limited. Most of what we believe to happen in the human is by analogy with research findin...

The 'clonal selection' approach to optimization - an abstraction of immune system adaptation, popularized mainly by de Castro and Von Zuben - may have reached something of an impasse. The method requires several parameters that must be tuned, and it normally uses a binary representation that can limit the accuracy of the results. This paper examines the uses and drawbacks of clonal selection, and suggests some ways forward, based on an analysis of the operators for choosing the amount of mutation and the number of clones. As a result, an effective, real-valued, parameter-free clonal selection algorithm is introduced, called adaptive clonal selection (ACS).
